I thought the same thing when I built mine. It sounded pretty wicked. But, trust me, after a while, you won't like it so much. You'll be wanting to make it quieter.bdeemo wrote:Ah I already routed that to the side, pointing at the water using the jetski's original exhaust port. Honestly it's not that loud! Way quieter than my outboard, I love the sound.PSG-1 wrote:It's a labor of love, for sure. But in the end, it's well worth the effort!
While you're at this point, you might want to go ahead and route the exhaust into the jet tunnel, then put rubber skirting around it. You'll be amazed at how much this will reduce your sound signature.
Good news is that it's still not too late to do a little modifying to make it quieter. Where the exhaust exits the boat, you could fabricate a small box/tunnel to fit around the exhaust hole. Basically 4 sides, with the front side attaching to the boat, (create a flange, and rivet it to the boat) and the back end open. Make it about 4-6" longer than the transom, but don't have it sticking out any farther than the steering nozzle of your jet pump.
Make a flange around the rear opening of the box, using some aluminum angle, and rivet it in place. Then, take some thick rubber, and make some skirting to fit the opening of that box. Since it's a little different that routing it through the jet unit tunnel, I would make it where the bottom edge of the skirting is the flexible part. Attach the rubber skirting using SS bolts with washers.
This will work almost as effectively as routing it into the jet tunnel.
